Title: Method of collaborative design, its device and its system
Inventor: CHARTIER VALENTIN
IPC: G06F17/50
Filed: 2002-06-24
Abstract: PROBLEM TO BE SOLVED: To provide high productivity and synchronous collaborative design by CAD modeling. SOLUTION: A non-centralized communications framework makes 'synchronous' collaborative design possible. Users are resident at workstations that are connected in a peer-to-peer arrangement and a model is resident in memory at each workstation in a collaborative design session. Modifications are made at the workstations and commands which are interpreted at each workstation to effect the modifications are transmitted over the network (51a, 51b). In addition, cell descriptors may be used to identify one or more geometric cells of the model (54a, 54b). The cell descriptors are in the form of scripts specifying constraints or filter for identifying cells.  The constraints are based on characteristics of items in the model or associations between items in the model, that are readily discernable to the user and are therefore easily written and susceptible to easy distribution to other systems.
